Xfinity WiFi hotspot will not load certain webpages

I have seen and read another post with the same problem I am experiencing. I am connected to a hotspot that i use quite often, but as of a few days ago it will not load certain webpages. some pages work fine as usual but others tell me "Safari cant find server." I have tried in chrome also and have the same problem. some examples are Hulu.com, slack.com, hotspots.wifi.xfinity.com, some .gov and .edu. This problem is consistent across multiple devices. 

I have gone into my account, removed all devices that were registered with my hotspot log in, rejoined to no avail. 

It seems like a very broad parental block almost, but it is hindering me from using the hopspot service the way I am used to.
